Truck would start and run, but if shut off would not restart for a while. Changed fuel filter, not it won’t start at all. Gets fuel pressure, pump works. Starter fluid won’t even get it to chug, now.
Thanks for the heads up. I’m going to stay away from 2006 F-150’s.
So this means it is an ignition problem. What kind… well hard to say since you didn’t tell us what engine you have. I suspect a failed crankshaft position sensor but that is a wild donkey guess.
